- Abstract
Background: With the increasinly intensificaction and commercialization of aquaculture production, diseases and infections appear, becoming a problem for the cultivation of many acuatic species including tilapia, being the antibiotics the way of control, which continuos use, have induced the appearance of multiresistent antiobitic strains. For this reason a way to contrarest, this effect is using probiotic strains that have several benefits over the animal wellness. Objectives: To evaluate the microbiological quality in tilapias fed with a formula plus probiotic and without probiotic.Methods: A diet was performed with and without probiotics, both with 42 % of crude protein, 95 % of digestibility and Energy 4765.8 Kcal/ kg; the probiotic was included at 1%. The experiments were conducted at the experimental station of the Corporacion Universitaria Lasallista; 631 animals were divided in four groups, two with probiotics and two without probiotics, the assay lasted five months. At the end of the assay, two animals per group were slaughtered randomly in four sampling, determining total and fecal coliforms, molds and yeasts, Gram positives coccus and Vibrio sp in samples of carcasses, skin and intestine for both treatments. Results: Not presence of Vibrio sp and molds were found. The counts of coliforms and mesophiles in the fishes samples presented significative differences (p<0.05), decreasing the counts in each evaluation time in the tanks with probiotics. Gram-positive coccus population and yeast did not show significance differences among the treatments (p>0.05) remaining stable during the assay. Conclusions: The count of coliforms decreased over the time in the animals fed with probiotics fulfilling the conditions of food safecty for human comsumption.
